Abstract: A current sensor is provided that employs a primary winding that carries the current to be measured, and a secondary winding that controls the flux inside the magnetic core, provides a sample of the primary current, and also helps to control the flux at small primary currents and to saturate the transformer. An auxiliary winding is optionally used to control the flux in order to simplify control of the sensor. By periodically applying a certain voltage at the secondary winding, the transformer core is forced out of saturation, and a sample of the primary current is taken by a sensing circuit that may include a sample-and-hold circuit and an analog-to-digital converter. A control circuit is employed to control the currents flowing in the secondary winding and optional auxiliary winding and to manage the sensing circuit.

Abstract: A transformer for high frequencies and high powers, in particular for clocked power supply units, consists of individual winding layers which during manufacture are wound around a thorn then covered with an adhesive plastic foil (2). The inner and outer diameters of the individual winding layers are selected to allow the individual layers to be nested into each other. The secondary winding for high intensity currents is made of a copper strip (5) cut out of sheet metal, for example, with a stepped shape when it is laid flat. The copper strip (5) consists of rectangular sections (6) interconnected by parallelogram-shaped sections (7). The copper strip (5) bears at both ends a tongue (8) with a hole (9).

Abstract: Proposed is a socket (1) which forms part of a flat-pin connector designed for 19" racks. Mounted on it by means of soldering tabs (3) is a standard circuit board (2) which is fitted in a housing (9). The housing (9) has two parallel walls (13, 14) and is closed off from the socket by a half-frame (16). The part of the socket (1) facing towards the circuit board (2) has a central section (6) which not only carries the soldering tabs (3) but also acts as a stop for the circuit board (2). The dimensions and position of this central section (6) are such that the housing wall (13) which covers the solder side of the circuit board does not extend out more than a distance RŸ- defined by the distance between the pin array and the side of the socket (1), so that the whole of the rest of the width comprising nŸ- distances RŸ- is available for components and the other wall (14). The space available for components can be further increased by providing over the shoulder (10) as recess (12) which allows the circuit board (2) to be mechanically fixed in place by means of rivets or bolts passing through a hole (11).
